The National Institute of Standards and Technology recently completed a multi-year study of three structural steel framing systems to evaluate the correlation between ASCE 7 and ASCE 41 as a part of its assessment of "first-generation" performance-based seismic design techniques. The results showed, in many cases, that a newly-designed building will not satisfy the assessment criteria in ASCE 41. However, it was uncertain whether the newly-designed buildings were indeed meeting the intent of ASCE 7 (i.e., no greater than 10 % probability of collapse given a risk-targeted maximum considered earthquake). Therefore, in this paper, incremental dynamic analysis is carried out on a set of six steel special moment frames to gain a more complete understanding of the collapse probability of current code-compliant buildings. The results are explored and then used to scrutinize the performance indicated by the ASCE 41 assessment. Various analysis assumptions are also examined to demonstrate the sensitivity of the collapse probability prediction.
